Gallivanter
A traveler who acts like they're from the city, but really just shows up and expects everyone to know who they are. They're loud, they're obnoxious, and they're not leaving until they take a picture with every local.
That Gallivanter took over the whole coffee shop just to get a latte and a picture with the barista.
This Gallivanter showed up at the museum and started talking to the security guard like they were best friends.
The Gallivanter tried to flirt with every shop owner in the city and then left a tip in every trash can.
